Adobe AD0-E722 Exam With Confidence Using Practice Dumps

• Option A is correct because enabling the config flag under deployment/blue_green/enabled is one of the steps to ensure zero downtime during the deployment process of Magento 2 on-premises. This flag enables the blue-green deployment feature, which allows deploying a new version of the Magento application to a separate environment (blue) without affecting the current live environment (green). Once the new version is ready, the traffic can be switched from green to blue with minimal or no downtime1.
• Option C is correct because running bin/magento setup:upgrade --keep-generated is another step to ensure zero downtime during the deployment process of Magento 2 on-premises. This command updates the database schema and data without deleting the generated code and static view files. This way, the Magento application can still serve requests from the cache while the database is being upgraded2.
• Option B is incorrect because running bin/magento setup:upgrade --dry-run=true does not upgrade the database, but only checks if there are any errors or conflicts in the database schema or data. This command can be used for testing purposes, but it does not affect the deployment process or the downtime3.
• Option D is incorrect because there is no such option as --convert-old-scripts-true for the bin/magento setup:upgrade command. This option does not exist in Magento 2 and does not have any effect on the deployment process or the downtime.
• Option E is incorrect because there is no such config flag as developer/zero_down_time/enabled in Magento 2. This flag does not exist in Magento 2 and does not have any effect on the deployment process or the downtime.

This action is necessary to make the attribute available for content staging and preview. According to the Adobe Commerce documentation, the catalogstaging_category_update_form.xml file defines the fields that are displayed in the Scheduled Changes section of the category form. The file extends the category_form.xml file and adds additional fields that are specific to content staging, such as start and end dates, campaign name, description, etc. To include a custom category attribute in the Scheduled Changes section, the attribute must also be declared in the catalogstaging_category_update_form.xml file with the same configuration as in the category_form.xml file.

According to the Adobe Commerce documentation, the Source Selection Interface is the main interface for implementing custom source selection algorithms. The interface defines a method called execute(), which takes a list of items to be shipped and a stock ID as parameters, and returns a SourceSelectionResultInterface object, which contains the recommended sources and quantities for each item. The Architect can create a new class that implements this interface and provides the logic for finding the lowest-cost warehouse that is open for each item. The Architect can then register the new class as an option for the source selection algorithm in the di.xml file of the custom module.
